Ultimaker 2 heated bed error

Recommended Posts

Posted · Ultimaker 2 heated bed error

Hi All,

 

My UM2 heated bed has stopped working. It constantly says its 27C if i manually heat it up it wont go any higher.

 

I have:

resoldered the 4 pins to the heated bed - they all looked ok tbh though

Checked the board connections - no issues there.

 

I have checked the current running through the board to the heater no issue and also the current at the heated bed end and im getting a readout on all the pins so cant see an issue there.

 

I havent been rough with the machine at all, could it just be the heated bed has died? The printer has been running close to 10k hours.

What resistance do you get at the connection on the heated bed with a multimeter at room temperature?

Sorry, I haven't logged on in a couple days. 832 sounds way off. Here are the points to measure:

Oh no that wasnt a dig at you, i just remember a year or so ago you would get 5 replies to  question like this.

 

So i have a sneaking suspicion im using my multimeter wrong for measuring resistance. I will take a look at a guide.

ok At A its a bit random it seems to fluctatute between no reading and around 109.4

At B i get nothing which seems strange?

at c i get very similar to A

That's a bit weird. It could be that the connection on the bed plate has gone out. To make sure I'm not missing any steps:

* When trying to heat, the button rotations are showing on the screen that temperature is being set (even though it's not reaching that temperature)?

* Is it giving you any sort of error message when you try to heat and it fails?

* Is there any sign that your Bed Heater Cable has the insulation caught in the green terminal block on the electronics board?

* Can you confirm that the Heater 2 and Temp 2 connections on the board are all empty?

* How long have you had your printer?

Answering your questions in order:

 

1.) The printer will start its warm up to get ready to print, but will never actually print as the bed isnt warming up. So i manually decided to see if i can change the bed temp. I can set it to higher but it will never get higher then a reading of 25-28 which seems a bit off anyway.

2.)No error

3.)No i think that all looks fine, at the weekend i can remove reseat the cables on the board

4.)yes

5.)Oh a long time, its a real work horse (it has been used for thousands of hours)

I just replaced the printbed in the end with a cheap one from china, works just as well as a legit one been using it for a few weeks. £10 instead of £100
